Surface treating device with cartridge-based cleaning system

Abstract

A cartridge is disclosed comprising a reel-to-reel roll of cleaning material, for use in a hand-held or robotic cleaning device. The cartridge provides either an electrostatic dust cloth or wet mop, and includes a fluid reservoir for maintaining the wet mop cloth during use. A dust bin is also provided on the cartridge, and includes a hinged lid for providing selective access to the dust inside of the bin. A motor, optical sensor, and fluid pump inside of a cleaning apparatus control the operation of the reel-to-reel cloth, and control fluid delivery to the wet cloth.
